GEYER, AND E. L. SEYMOUR.

NAUTICAL ALARM.

Specification of Letters Patent No. 16,776, dated March 3, 1857.

To all whom it may concern Be it known that I, EDWARD L. SEYMOUR, of the city and State of New York, have invented a new and improved mode of constructing nautical alarms to be applied to buoys and vessels with a view of preventing shipwrecks on the coasts and other dangers arising from the collisions of vessels in foggy weather and storms, and do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, and the letters of reference marked thereon, making part of this specification.

a, a, a, a, a, a, a, 54, represent a frame work of metal, or any other suit-able material, in, or about the middle of which is placed a cross-piece b, b, b, b, so arranged as to hold in suspension, by means of wires, ropes, chains or otherwise, so as to let play freely in any or all directions, a pendulum rod 0, c, with the weight (Z, attached to the lower end of it.

Upon the pendulum rod, and above the point of suspension 6, is placed a ring f, (which can also be replaced by a polygonal plate or frame, a ball, a cone, a series of arms proceeding from the center or any other contrivance answering the purpose) acting upon two, four, or any desirable number of levers g, g, (with, or without, broken joints in them) which are attached, each, to an elastic rod of metal or other material, with striking hammers 71, h, 71., h, 72, 7t, 72, h, (on one or both ends). These hammer rods play freely on axles i, 2', supported by the frame work above mentioned.

70, 7c, are one or more gongs, or bells (attached to the frame work, which can be made to be struck on the out or inside, accordingto the position in which they may be placed, or the manner in which the hammer-rods may be bent, or attached to the frame and levers.

Z, Z, represent springs of any suitable construction, and so arranged and attached as to cause the hammers, after having been drawn back by the action of the pendulum and levers, to return to, and strike the gongs with an elastic force.

m, m are pieces or stops, placed transversely to the hammer-rods, the object of which is to regulate the distances of the hammers from the gongs or bells, and to allow the necessary vibration thereof.

The apparatus, as above described, is to be placed upon a buoy, boat, or other float, which, when acted upon by the tossing of the waves, will cause an opposite and repeated oscillation of the frame-work and pendulum, making the hammers to strike upon the gongs or bells, in whatever direc tion the float may be moved.

hat I claim as my invention and desire to secure by Letters Patent is The combination of frame, rods, hammers, axles, springs, pendulum, levers and gongs or bells, substantially as above described, to be placed upon buoys, floats, or vessels of any kind, for the purpose of causing alarms and giving warning of rocks, shoals, or other dangers upon the coasts or at sea; and I do not mean to confine myself to any particular materials in the construction of the same nor to the placing of the ring, levers and springs above or below the center of oscillation, but to vary the position of the same, and of the gongs and their number, as I may deem desirable, so long as I adhere substantially to the above description.
